 Anther & filament of stamen- The anther and filament of the stamen is where the pollen is produced and carried until a pollinator comes by and takes the pollen to another flower. The anther is where the pollen is specifically held in the flower, and the filament is a small stem like structure that holds up the anther up higher.
 Auxin producing area of plant- the new flower bud on the tip. This is where auxin is produced. Auxin is a hormone that is made by plants in areas where a new root or shoot is growing, which is exactly what is happening here.
Cambium- The cambium is a very thin layer of growing tissue that produces new cells that become either xylem, phloem or more cambium. Every growing season, a tree’s cambium adds a new layer of xylem to its trunk, producing a visible growth ring in most trees. The cambium is what makes the trunk, branches and roots grow larger in diameter.

 Detritivore-An organism that feeds on and breaks down dead plant or animal matter, returning essential nutrients to the ecosystem. Detritivores include microorganisms such as bacteria and protists as well as larger organisms such as fungi, insects, worms, and isopod crustaceans. This is a picture of a rolly polly which are under this category.  
 ATP- This picture is of a plant in my yard it's an example of an organism that synthesizes ATP. ATP is a compound existing of nucleotide adenosine attached through its ribose group to three phospharic acid molecules. Its an energy source produced during photosynthesis in plants and cellular respiration.
 Glycogen-A substance deposited in bodily tissues as a store of carbohydrates, a polysaccharide that yields glucose on hydrolysis. Spaghetti comes under this category. 

 Ovary- In flowering plants, an ovary is a part of the female reproductive organ of the flower or gynoecium. This is a picture of a rose bud. 
 Radial Symmetry- Symmetry around a central axis, as in a starfish.
 Dominant vs. recessive phenotype- These flowers are located in a flower pot in my backyard. They are the same species of flower but they have different phenotypes, or observable traits. Obviously the two different colors are different phenotypes and depending on the type of plant one color may be the dominant phenotype while the other is the recessive phenotype.
Stigma and carpel- One of the leaflike, seed-bearing structures that constitute the innermost whorl of a flower. One or more carpels make up the pistil. Fertilization of an egg within a carpel by a pollen grain from another flower results in seed development within the carpel. the carpel is the female reproductive organ of flowering plants, consisting of an ovary, style (sometimes absent), and stigma. The carpels are separate or fused to form a single pistil.
